RUN (module passivation): Alternating blinking of ERR1 and ERR2 LEDs
PROFIsafe communication is up and running. The safety application is running with a present module error.
The module and, as a result, all its channels are passivated. Possible reasons for module passivation are:
n PROFIsafe communication failure (CRC error)
n PROFIsafe watchdog timeout exceeded
n Undervoltage/overvoltage detected (Device_Fault status bit = 1)
The fail-safe value "0" is transferred to the Safety PLC for all passivated input channels, if the connection to
the PROFIsafe F-Host is possible. The safety application continuously attempts to establish a communica-
tion to the Safety CPU, if the communication is broken. All passivated output channels have a state of "0".
A state transition to another RUN mode is only possible if the detected error is gone.
PROFIsafe status bits in the F-Host for Safety I/O module (if communication is possible!):
OA_Req_S = 0
FV_activated_S = 1
Device_Fault = 1 (in case of undervoltage/overvoltage detected) and/or CE_CRC = 1 (in case of communi-
cation error) and/or WD_timeout = 1 (in case of watchdog timeout)
Process data bits in the Safety I/O module process image:
PROFIsafe diagnostic bit = 0
Channel process value = 0
Reintegration request bit = 0
